Application filed August 10, 1915.

T 0 all whom it may concern Be it known that I, VINCENT W.*WECZER ZICK, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Sound Control for Talking- Machines, of which the following is a full, clear, and exact description.

This invention relatesto attachments for talking machines'and particularly to an irnproved device for controlling the volume of sound thereof.

Another object in view is to provide a device for controlling the volume of sound arranged in the gooseneck of the talking machine or at some other convenient point in any part of the quantity or volume of sound tube, whereby the tone is affected according to the movement of the controlling device.

A still further object in view is to provide a pneumatic bulb in the sound tube or the gooseneck of the talking machine and connected therewith a tube and bulb whereby the bulb in the sound tube or gooseneckmay be inflated or deiated at will and to any extent for varying the volume of sound according to the particular temperament of the person operating the device.

In the accompanying drawings: Figure 1 is a top plan view of a talking machine with an embodiment of the invention kapplied thereto; Fig. 2 is a sectional View through a gooseneck and part of the sound tube of a talking machine with an embodiment of the invention positioned therein; Fig. 3 is a view similar to Fig. 2 but with the control bulb distended; Fig. 4 is a detail fragmentary sectional view on line 4-4 of Fig. 2 showing the width of the bulb as distendcd as being less than the width of the gooseneck.

Referring to the accompanying drawings by numerals, 1 indicates a casing of a talking machine, which may be of any desired type, and 2 a record. The needle or stylus 8 of the machine engages the record 2 in the usual manner and is vcarried by the sound box 4 which in turn is carried by the gooseneck 5 swiveled on the tone tube 6 mounted in any suitable manner at 7 on one side of the casing 1. The detail construction of these parts of the talking machine is well Specification of Letters Patent.

known and consequently forms no part of the present invention.

In swiveling the gooseneck 5 in position a nut 8 is provided which may be easily applied and removed at any time. Extending through nutl 8 is a tube 9 to which a pneumatic bag 10 is secured. The pag or bulb 10 is preferably of a good quality of thin rubber and when deflated appears in section as shown in Fig. 2 or in plan as shown in Fig. 4. It will be observed that the bulb 10 does not touch the gooseneck 5 unless distended by having air forced therein, as shown inv Fig. 3. As the air is forced in through tube 9 the bag or bulb will begin to take a globular form, as shown in dotted lines in Fig. l, and consequently partially lill the gooseneck 5 without, however, touching the walls thereof, thus varying the quantity or volume of soundto a greater or less extent according to the inflation of the bag. When the bag is inflated until the same presses tightly against the walls of the gooseneck 5 the sound yis completely shut olf or, rather, is shut ofi as much as possible so that only a small sound will be transmitted to the horn or sounding board of the machine.

Preferably the tube 9 is metal, though it may be any other suitable material, and is arranged to extendinto the bag 10 as more particularly shown in Fig. 3 and be secured thereto in any suitable manner, as for instance, by an adhesive or a winding of thread or cord. The outer end of the tube 9 is enlarged at 11 so as to spread the flexible air tube 12 as shown in Figs. 2 and 3. Tube 12 may be of any length so that a person may be positioned at a suitable distance from the talking machine and yet be in a position to operate the bulb 13 which acts in a certain capacity as a pump except that it is preferably not provided with a valve, so that when it is collapsed air is forced into the bulb or bag 10 and when the bulb is released the air is withdrawn from the bag 10. In order that v,there will be no accidental vjerking or movement of the tone tube 6 by reason of a pull on the tube 12, a hook 14 is fitted over the pivotal member 15 provided on the machine 1. The hook 14 is also provided with loops 16 and 17 through which the tube 12 is passed, as shown in Fig. l, so that if any one gives an accidental pull to the tube l2` the same willy bulb 13 and press the same at any time and' to any extent for modulating or controlling in any way the volume of sound according to the particular temperament or moodV of the person using the device. It will be noted that the device mav' be quicklyl applied andi removed whenever desired so-that if any` one does-not wish to use the device the same may remain idle and4 on the machine or may be removed and a new nut 8 substituted Jfor the nut 8 having the tube arranged@ therein.

lVhat I claim is:-`

1. In a sound controlling device, the com bination with a talking machine having sound tubes, of an;y inflatable member arranged in said sound tube, and means eX- tending to aA distance for inflating said inflatable member and thereby` varying the volume of sound passing through the sound:

tube.

2. A sound controlling.Y device for talkingmachines, comprisingV an cXpansible bulb,

adapted to be insertedv into the sound carry.'-

ing tube of atalking machine, and. means;

arranged exteriorlyv of saidtube for inlatf ing and deating said bulb whereby the volume of sound may be varied according to the desire of the operator.

3. A sound controlling device comprising an` expansible bulb or bag, atube of an appreciable length connected therewith, and a bulb connected' with said tube, said last mentioned bulb being adapted t0 be collapsed by the hand for inflating the first mentioned bulb. or bag.

1. A sound controlling device comprising an elongated inflatable bag adapted to be fittedv into thel gooseneckofA al talking machine, said bag being ol less width than the diameter olsaid gooseneck, aI tubular member fitted into the retainingTv screw of* the gooseneck and. extendingl into saidA bag, a `flexible air tube connected with said tubularmemben, and ay hand, bulb connected with said flexible tube whereby when said handy bulb isy collapsed air will be forced into said bag for inlatingthe same, theinlation of said bag corresponding to the deflation.y

of said hand bulb.

In testimonyl whereof I' have signed my nameto this specification, in thefpresenceo two subscribing witnesses.
